UPDATE: Reader Michael Ryan emails: “If you are healthy, somebody along the line gave you some help. There was a great doctor somewhere in your life. Somebody helped to create this unbelievable American medical system that we have that allowed you to thrive. Somebody invested in bikepaths and broccoli. If you’ve got a healthy body — you didn’t build that. Somebody else made that happen. Cyclosporine didn’t get invented on its own.”
